Microwave drying, puffing, and sterilization provides an efficient processing solution for mealworms, black soldier fly larvae, silkworm pupae, and other insect products. With fast and uniform heating, it can quickly remove moisture, reduce microorganisms, and shorten drying time while improving production efficiency and product quality.
The microwave system can also provide a certain puffing effect according to different processing requirements. It can be customized for different insect species, moisture levels, final product requirements, and production capacities, making it suitable for insect food, protein powder, animal feed, pet food, and other applications.
Our industrial continuous microwave dryer and sterilizer provides an efficient drying, puffing, and sterilization solution for mealworms, black soldier fly larvae, silkworm pupae, and other insect products. Microwave energy generates heat directly inside the material, enabling rapid and uniform moisture removal while helping reduce microbial levels, shorten drying time, and improve overall processing efficiency. The microwave process can also create a certain puffing effect to improve the texture and appearance of the dried insects. The system can be customized with different microwave power levels, conveyor speeds, temperature settings, and control functions according to the insect type, initial moisture content, target moisture level, sterilization requirements, and required processing capacity.

This air-cooled tunnel microwave dryer is designed for continuous industrial processing. Using microwave volumetric heating, it heats materials from the inside, enabling efficient and consistent drying throughout the production process.
The equipment is constructed from 304 stainless steel and uses air-cooled magnetron units for reliable operation. Its PLC control system allows independent adjustment of microwave power and conveyor speed in different sections, making it suitable for stable, standardized, and continuous production in industrial facilities.
Fast and Efficient Drying
Microwave energy directly heats the moisture inside mealworms, black soldier fly larvae, silkworm pupae and other insects, accelerating moisture evaporation and significantly shortening drying time.
Uniform Heating
Microwave volumetric heating allows the material to be heated from the inside and outside simultaneously, helping improve drying uniformity and reduce uneven moisture distribution.
Drying and Sterilization in One Process
During microwave drying, thermal and microwave effects can also help reduce microorganisms, allowing drying and sterilization to be completed in the same processing line.
Good Puffing Effect
Rapid internal moisture evaporation can create a certain puffing effect, helping improve the texture and appearance of dried insect products.
Continuous Industrial Production
The conveyor-type design enables continuous feeding and discharging, making the machine suitable for medium and large-scale insect processing lines.
Adjustable Processing Parameters
Microwave power, conveyor speed, temperature and processing time can be adjusted according to different insect species, moisture contents and final product requirements.
Easy Operation and Automatic Control
The system can be equipped with PLC and touchscreen control for convenient parameter setting, temperature monitoring and continuous production management.
Customizable Production Capacity
Machine size, microwave power, conveyor width and production capacity can be customized for mealworms, black soldier fly larvae, silkworm pupae and other insect processing requirements.

This continuous microwave drying, puffing and sterilization machine is designed for efficient processing of mealworms, black soldier fly larvae, silkworm pupae, crickets and other edible or feed insects. Microwave energy generates heat directly within the insect material, enabling rapid moisture removal and uniform heating while helping reduce microbial levels, shorten drying time and improve processing efficiency. Rapid moisture evaporation can also provide a certain puffing effect according to the insect type and processing parameters.
The continuous conveyor system supports stable feeding and discharge and can be integrated into automated insect processing, animal feed, pet food and insect protein production lines. Microwave power, conveyor speed, processing time and temperature can be adjusted according to different insect species, initial moisture content, target moisture level, sterilization requirements and processing capacity.
